– The meter currently checks the value of the introduced parameter at the mo-
ment. In case when the introduced value exceeds the upper or the lower range
of changes given in the table 1, the meter will not make the parameter record.
– In case of the
Input type
change, a simultaneous change of the decimal point
follows, optimally for the given input.
– After the supply decay, the current time is reset.
– The recording switching off follows in following cases: switching the recording
off from the programming matrix, change of the
input type
,
change of the
recording time start
or the
recording time interval
, setting
Cnt
=0, filling of
the memory, and at a renewed switching of the meter on to the network.
– In case of a
Intr
or
Sect
bargraph type, it is possible to set only one
CurL
and
Curh
markers (from one alarm). The others are automatically erased.
– Max and Min values are erased in case of changes: input type, individual cha-
racteristic (on, off), writing of standard parameters.
